MEDIA SIGNATURE RECOGNITION WITH RESOURCE CONSTRAINED DEVICES
This abstract first appeared for US patent application 20250016388 titled 'MEDIA SIGNATURE RECOGNITION WITH RESOURCE CONSTRAINED DEVICES
Original Abstract Submitted
the present invention recognizes media content using signatures generated by network devices with limited processing power. an audio signal is prepared for application of a discrete fourier transform (dft). outputs from the dft include real components and imaginary components that are used to calculate output magnitudes associated with frequency bins. the frequency-amplitude pairs include the output magnitudes and the associated frequency bins. a signature of the audio signal is generated by selecting a predetermined number of frequency-amplitude pairs having dominant output magnitudes. the network devices that generate the signatures may transmit the signatures to a server for analysis. the server may trigger actions in response to detecting known content based on the received signatures matching known signatures.
